ATTORNEY Patented May 12, 1933 UNITED STATES PATENT OFFICE DISPENSING BOTTLE STOPPER Application filed September 8,1927. Serial No. 218,209.

My invention relates to dispensing stoppers and more particularly to devices of this character adapted for use with a container for liquid under pressure, the principal object of the invention being to provide for dispensing portions of a gas-impregnated liquid without admitting air to the container, and to securely engage a dispensing stopper with a container by easily removable means.

In accomplishing these and other objects I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of the neck of a bottle equipped with my improved dispensing stopper, the securing means being shown in unlatched position.

Fig. 2 is a similar view showing the securing means in latching position and the bottle inverted for dispensing.

Fig. 3 is a vertical, central section of the device through the outlet elements and handle of the securing element.

Fig. 4 is a vertical section on the line 4-4,

fieferring more in detail to the drawings: 1 designates the neck of a bottle, having an annular boss 2 adjacent its mouth, and 3 is a stopper, preferably of elastic and flexible material such as rubber, for insertion into and closing the mouth of the bottle. The stopper is provided with an annular shoulder 4 for seating on the rim 5 of the neck. A cap element 6 is provided to fit over the top of the stopper having a peripheral skirt section 7 that seats upon said annular shoulder of the stopper, the skirt being urged upon the stopper shoulder to impress the shoulder against the rim by a retaining yoke or securing member 8, comprising a clamp having arms 9 by which it is pivotally mounted in opposite bearings 10 of the cap skirt, and being provided with a semi-annular flange or collar element 11, adapted for engagement 4 with the under portion of the boss 2 of the bottle neck. The retaining member is provided with a handle 12 for pivoting the member downwardly for engaging the semiannular flange with the rib. The securing member is so pivoted that the outer ends of the semi-annular flange project horizontally beyond the pivotal axis when the flange is positioned in en agement with the boss so that force must e exerted at right angles to the pressure of the contents of the bottle against the stopper and cap to dislodge the member for unlatching the cap from stopperretaining position. The skirt .7 of the cap bearing against the elastic stopper shoulder securely seals-the stopper in the neck of the bottle.

The stopper is provided with an axial bore 13 and into this bore extends an annular elastic and flexible packing ring 14, preferably integral with the stopper and positioned adjacent the upper end of the bore, which serves as the sealing element for a valve stem 15, positioned axially of the bore and reciprocable therethrough the stem having a valve 16 at its lower end seatable on the lower end of the stopper to close the lower port of the bore. The valve is urged to its seat by a coil spring 17 positioned on the stem exterior to the stopper and bearing against the cap and a head member 18, sc'rew-threadedly attached to the stem, whereby, when the stem has been depressed by pressure on the head against the influence of the spring to open the port, the spring upon release of the head will return the valve to closing position.

An outlet channel 19 extending preferably in an angular direction from substantially the longitudinal center of the bore to the upper edge of the stopper, is provided therein, having a port 20, the annular packing ring being provided in a position between the point of communication of the channel with the bore and the upper end of the bore so that' when the valve is open, liquid may enter from the bottle into the bore and pass therefrom outwardly through the channel. The cap 6 has a spout 21 positioned for communication with the channel 19 of the stopper.

The parts being provided as described, the cap member being positioned on the stopper and the valve element installed therein, the stopper may be inserted into the mouth ofthe bottle and passed therein to approximately its final position, its shoulder resting upon the rim of the bottle neck. The outer ends of the semi-annular flange of the retaining yoke will then be in a position for engaging the neck rib, and downward ressure on the handle element will cause t e flange to be depressed to slide under the walls of the rib, and due to the relation of the pivots to the axis of the bottle, be projected into engagement with the rib. The yoke member Wlll be latched in engagement with the neck rib against accidental removal by influence exerted longitudinally of the bottle. The bottle is inverted for service and the valve stem depressed to 0 en the interior port of the stopper, the va ve stem sliding over the inner surface of the axial packing ring, so that liquid may enter the bore and depart through the channel and spout, the gas inthe mixture assisting in expelling the liquid and part thereof departing with the liquid. When pressure on the stem is released, the stem returns to normal position to seat the valve on the port to close the bore and the channel.

The stopper, having preferably slight frictional engagement with the neck of the bottle, may easily be removed, for refilling the bottle, or other purpose, by displacing the cap yoke, and lifting the cap and stopper.

My device is particularly adapted, therefore, to dispensing a portion of the carbonated or otherwise gas-impregnated contents of the bottle, while preventing air from admission thereto which would tend to depreciate the quality of the liquid, and cause it to become flat, stale and unpalatable.

The structure provides for the secure retention of the stopper in the bottle, and the sealing of the stopper in engagement with the bottle, while permitting easy removal.

What I claim and desire to secure by Letters Patent is:

1. A dispensin bottle stopper including an elastic channe ed body adapted for location in a bottle neck and having an annular shoulder for engaging the rim of the neck, a ca on said bo an attaching member on said cap having a cam portion engageable with the bottle neck to press the shoulder against the neck rim and retain the stopper, and a valve controlling outlet through the body channel.

2. A dispensing bottle stopper including an elastic ody having a longitudinal bore, an outlet channel leading from said bore, and a packing ring extended into the bore outwardly' o the channel and in the direction of the intake end of the bore, a cap in said body having a nozzle in communication with said channel, a valve stem extended through said bore in frictional engagement with said packing ring, a valve on said stem, a spring urgin the stem to seat against the end of said bo y to close said valve, and means on said cap for retaining the body in a bottle neck.

3. A dispensing bottle stop r including a cap, an elastic apertured bo y mounted in said cap and having a portion extending from said body for engagement with the rim of the bottle neck, and means pivotally movable on the cap into en agement with the neck of the bottle to urge t e cap against said portion to compress the portion against the rim of the neck and lock the cap to the body.

4. In a bottle stopper, including an elastic body adapted for projection into the neck of the bottle and having an annular shoulder engageable with the rim of the neck, and a cap onv the body, a latching member pivotally mounted on said cap and having a cam flange movable into engagement with the bottle neck upon pivotal movement of the member to press the shoulder against the neck rim and retain the stopper.

5. In a dispensing bottle stopper including a cap having a valve stem opening and a nozzle opening, an elastic sealing member mounted in the cap and having a central opening for flow of liquid from the bottle toward the nozzle opening, and adapted to engage the rim of the bottle neck, a latching member pivotally mounted on the cap and having a portion engageable with the bottle neck for latching the cap to the bottle, and a valve controlling flow of liquid from the bottle toward the nozzle opening.

6. In a dispensing bottle stopper including a cap having a cylindrical skirt and a nozzle extending angularly to the axis of the skirt, sealing means including an elastic annulus receivable in the skirt and adapted to seat on the rim of the bottle neck, means includin a valve having a stem slidable in the cap or controlling ow through the nozzle, and an attachin member pivotally mounted on said skirt an having a cam portion engageable with the bottle neck to press said annulus against the neck rim and retain the cap.

7. A dispensing bottle stopper including an elastic channeled body adapted for location in a bottle neck, a nozzle member havin a nozzle in communication with said channe a latchin member movably connected with said nozz e member and having a flange, the latching member being movable in relation to the nozzle member to engage said flange with the neck of the bottle and compress the elastic body against the neck, and a valve controlling outlet through the body channel.

In testimony whereof I aflix m si FREDERICK ature.
